is invention relates to incinerators Lille characters of reference refer to like oying refuse and garbage, and its main parts in all the iigures of the drawings, object is to provide an improved apparatus As illustrated in the drawings, my imof this class, particularly for the sizesadaptproved incinerator is constructed with a cas- 5 ed for apartment and household use asivell ing' 1 mounted on legs 2 and provided With a as larger sizes for other uses. A. special obhinged lid or cover 8, by means t which the ject is to provide convenient means for dis-' refuse holders or compartments l and 5 can posing of the ashes formed in the incinerator, be filled with garbage and refuse. The casvvithout clogging the active parts of the same. ing 1 is provided with outer and inner Walls Another object is to provide a lid or cover for 6 and 7 which I have hereinafter referred to the incinerator Which prevents the escape of as the double Walls of the casing, and there smoke and gases into the room during the is a passage 8 between said Walls for the flow normal operation of the incinerator. Still of cool air for reducing the temperature of I another object to provide means for more the outside wall of the casing and for prethoroughly drying the refuse, garbage, etc. venting theescape of products of combustion and to then ignite the same, and to provide an through the interstices between the casing improved fine or fines for efiecting equal and and the edges of the lid or cover 3. The eificient distribution of hot gases and prodsaid lid is provided preferably with triple acts of combustion during the incinerating Walls,such.as 9, 10, and 11, held together by operation... suitable means such as the screws 12, with The means I prefer to employ'it'or accomsuitable spacing members 13, There is an plishing the above-named objects, together iinperforate Wall 14 at the side of each of the with other advantageous features of my imrefuse holders or compartments 4 and 5. proved incinerator, are illustrated in the ;There is an encircling opening or air inlet drawinp's accompanying and forming part 15 atthe bottom of the casing 1, and a re- 7 of this specification, and in \vhich stricted and encircling outlet 16 at the up- Figure 1 is a vertical section ofiny in1- per part of the casing.

flow of combustion products and gases will be downward through the wall passage 8 in a direction reverse to the normal flow and thence tln-ough the inlet 15 and then upwarc into the interior of: the incinerator as through the tines 26. this action applies t slight cloggings such as at first lighting the incinerator due to a cold chimney or a chimney with a weak draft.

The refuse holder" or compartments and are constructed with ide walls 27 a d end formed as so to member 1: or grids, ch consisting of subsuintially upright bars iperfm'ationssuch est-l0. The said members is i and 28 have lugs 31 and bolts 3'53 and nuts 33, by means of which they are .ured together at the cc-rners of the common flue The grins or walls 27, an, 28, and walls 14 thus form a rectangular refuse space which is completed when the three grids 2'7, 28, 28, are lowered into place.

Each of the end members 28 is provided with a bearing 34 which supports one of the trunnions 36 of the grid or grate which forms the bottom or floor of the respective holder or compartment 4 or 5. The side members 27 are each provided with portions 37 forming a roof over the top of the common line 25. The said portions 37 slope downwardly toward the interiors of the compartments 4 and 5, tending to cause the flow of hot air and combustion products to follow the course indicated by the arrows 38. The action of the hot air and products of combustion is to dry the upper parts of the contents of the compartments 4 and 5.

There are lugs 39 on the inner casing walls 7 which support the compartments 4 and 5, and their side wall members 27 come together at the middle of the incinerator along the roof portions 37 and also along partitions 40 preferably two in number and dividing the common fine 25 into three parts. The object of the partitions 40 is to prevent diagonal flow of hot air and products of combustion, so that all parts of the contents of the com partments will be given a uniform drying el'fec'.

For effecting the drying and igniting of the contents of the compartments 4 and 5, I prefer to employ burners 41 for fluiu fuel such as coal gas. The said burners 41 are each provided with side holes 42, top 43, inclined roof 44, inlet pipe 45 for mixed gas and air, mixer 46, gas supply pipe 47, and stop cocks 48. There is a pilot burner 49 midway between the two burners 41 and connected to the gas supply pipe 47 and provided with a stop cock 50. Each of the burners 4i connected to its respective pipe 45 for supplying mixed gas and air, about midway of its length. Vith this construction the usual effect would be to cause a great flow of the mixture to the ends of the burner particu larly the right hand one in Fig. 6 and with too little of the supply going through the holes near the middle of the burner. To prcvent this action and equalize the flow of the mixture, 1 provide an abutment such as 5l which deflects the flow so that a portion of the supply that would otherwise go to the right hand end is diverted into the holes of the burner near the middle thereof and also more of the supply goes to the left hand half of the burner, so that the flow of gas and air is equalized throughout the burner and a more uniform effect is attained.

The outer end of each of the front trunnions 36 of the grates 35 is square in cross section, so that it fits the socket 53 of a shaker 52 provided with a handle 54 and locking lugs 55 and 56. A latch 57 locks the grate in its normal or level position by its locking portion 58 engaging with the lug 55 of the shaker 52, while the lug 56 engages the stop portion 59 on the stationary member 60. \Vhen the latch 57 is tripped, the shaker 52 can be oscillated by moving the handle 54 downwardly until the lug 55 engages the stop 61. A. groove 62 in the shaker 52 is engaged by the V of the stationar member and is thus held in proper position in the front wall 6 and also prevented from moving lengthwise.

T here is an observation door 63, by means of which the internal conditions of the incinerator can be watched when incineration is taking place, and the lid 3 provides a most complete and convenient means of inspection when there is no combustion going on.

Fig. 9 illustrates a modified construction of the lid, double casing walls, and the. restricted opening from the double wall air passages to the interior of the incinerator. It differs from that shown in Figs. 1 and 4 by having an angular member (34 in place of the T-member l7 and the depending flange 19 on the lid is nearer the interior of the incinerator.

Figs. 10 and ll illustrate a form of the invention where the lid 3 does not cover the whole top of the incinerator but there is a fixed plate 65 forming the outer part of the incinerator top and provided with an opening 66 over which the lid 3' shuts. An innor plate 67 is provided which extends the wall passages 8 to meet the flange 19' of the lid. so as to cooperate with it in forming a restricted passage for the incoming air.

Ordinarily l employ the burners 4i for effecting the drying and igniting of the refuse in the refuse hold. s or compartments 4 and 5, but I may also employ other means. if or instance, I may fill. the holders or compartments 4 and 5 with mixed refuse which would include waste papers, old magazines, and kitchen refuse and garbage, and then allow the mass to dry partially by the flow of air up through the incinerator from the open loottom of the same, through the grids 35, flues 25, 9.6, to the space over the compartments 4 bustion of the masses in the compartments 4.

and will follow without the useof gas or other additional fuel. It 1s not always necessary to light from below in such cases especiall I if there is much dry paper in the incinerator,as in that case it can be very satisfactorily lighted by dropiug a lighted paper from above the compartments, first raising 'the lid if the same isuse'd.

The incineration chamber or destructor chamber is the interior chamber 100 of the casing, whereof the upper parts are utilized for refuse destruction or incineration. and the lower parts for igniting the refuse in the construction illustrated and also for removal of ashes. The removal of ashes which collect in thelower parts of the holders or compartments a and. 5 may be effected in any suitable manner as by'placing an ash pan on the floor under the grid or grids 85 and dumping the latter by means of the handle or handles 54.

It is evident that the form and arrangement of the different parts may be modified and changed in various ways and I donot therefore confine myself to the exact details of construction and arrangement hereshown.
